IPC: B66F19/00
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of damage of an article and an article supporting base by providing a means for sensing the grounding of a suspended article, and controlling a driving motor at neutral on the basis of the detection of grounding, and operating an electromagnetic brake after the predetermined time is passed. SOLUTION: After an article is suspended by a suspending arm and raised for movement, when the article is placed on the ground or a supporting base, a grounding sensing means sense that the article is placed, and a CPU 22 controls a driving motor M at neutral. Even in the case where the downward force is applied to the suspending arm, this force escapes so as to eliminate the continuous pushing of the suspending arm to the article. Thereafter, elevation of the suspending arm is stopped for fixation by an electromagnetic brake B. Even in the case where the suspending arm is operated for lowering more after the suspended article is grounded, since the current value of the motor M rises, grounding of the article can be sensed by sensing a rise of the motor current. Namely, the current of the motor M is input from a current meter A to the CPU 22 through a motor current detecting circuit.

Title: Slowly closing mechanism of lid body on toilet bowl
Inventor: SHINOHARA KUNIAKI
IPC: E05F3/16
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To surely buffer in closing a toilet seat and a toilet lid by providing a rotor, a holding member, torsion bars, and braking rings. SOLUTION: In a closing state of a toilet lid 2 and a toilet seat, initial torsion is loaded on torsion bars 11, 12 so as to operate to open them by a restitutive force. On the other hand, O rings 9, 10 are in close contact with chambers 5a, 5b so as to operate a sliding resistance. The closed attitude can be thus held without floating by setting them to become larger than the restitutive force of the torsion bars 11, 12. When the toilet seat is closed already and the toilet lid 2 is going to be closed, the hinge shaft 4 is rotationally moved counterclockwise along with the toilet lid 2. The similar counterclockwise torsion is thus applied to the torsion bar 11 whose torsion load is set to zero. Successively, as the toilet lid 2 is falling, the reaction of the torsion bar 11 is operated so as to resist to the falling operation.  This constitution can loosen the working and assembling accuracy of respective members so as to reduce the production cost.
